I have a crossfire 2x2 table, upgraded with the water bed and to the 24"x33" size (like $150 upgrades each) and I've used it nearly every week since I bought it last October(ish). It is hands down one of the best tools I've ever bought. When it comes to fabrication, I would rank it only behind a welder and a plasma cutter for useful tools (maybe throw a grinder on that list lol). I bought $100 of brackets from Ruffstuff, and had been eyeballing it for awhile and said fuck it, I'll just buy the plasma table instead of spending another $100. Every single part on my buggy, and lots of other things, is now custom made on the fly for that application and turns out fucking amazing. The level of craftsmanship and ease that the plasma table brings can't be overstated (coming from someone who had never used one prior). I run mine with my Hypertherm 30XP. Other things you'll need if you get it is a laptop/computer, mach3 software to drive the electronics, and CAD/CAM to program it. Fusion 360 from Autodesk is free for hobbyists and only a few hundred bucks a year if you make money with it, and it does both CAD and CAM. Also, Langmuir has fantastic instructions and supplies all the codes you need to configure the CAM and Mach3 to talk to the plasma table and they have a huge forum with lots of info too. The whole process is very straight forward.
Cons, honestly not many. Langmuir is a great company, albeit relatively small. I know 3 other guys who bought Crossfires after me and have been very happy with their support. I have had literally 0 issues with mine, and I don't baby it. It sits in the corner and fires up when I need to use it and never skips a beat, at most I wipe down the bearing surfaces with WD-40 sometimes occasionally change the water in the table. The biggest downside to the 2x2 table is the cantilever arm can be finicky, over time it will not hold level, and getting the whole table to stay level with the arm in both axis can be difficult in general. Personally this is not a huge deal, I rarely do pieces larger than 12", but on large stuff sometimes I need to relevel the bed (the easier approach is to put little pucks under the plate and level it vs the whole bed). For 99% of what I cut, brackets, shock mounts, tabs, etc. there's no issue and the lack of Z-axis is not an issue (honestly not sure of the need for Z-axis). It takes a day or two to learn what the best cutting speed is and how to configure everything in the CAM fast, but once you get the hang of it you can literally draw something in CAD and program and cut it in the same amount of time as trying to cut it by hand, and it'll be flawless straight off the table and look like it was professionally cut. The only other "con" is with the smaller tables you need to cut down sheets of steel, I usually cut sheets into 2.5x4ft strips. Thickest I've cut is 1/4" steel and aluminum and it goes through it like butter and the cut quality is amazing, though that's more a function of your plasma and the speed you programmed in.
TL;DR -- I would buy another Langmuir plasma table in a heartbeat. If I walked outside and saw something fell and crushed it, I wouldn't hesitate to buy another one instantly (though maybe upgrade to their newer 3x4 table :D ). The 2x2 table, especially with the 2x3 upgrade and the water bed, is $2000 new and doesn't take up much space and will hold its own with expensive tables. 10/10 would recommend.
