I wish I would've found this post awhile back. I bought a pair of Nomads and the leaf a few months back. I kept going back and forth on it before I pulled the trigger. I almost want to say that I lost some sleep over it trying to decide what to do.
I have a welding table already that I built maybe 5 years ago but it slowly became a work bench w/ my vertical porta-band on it (swag), drill press, and vice. I also use it a lot to work on stuff (like rebuilding a head on top of a piece of plywood) so it wasn't very useful as a welding table anymore. I don't really have room for another table either, my 2 car garage is PACKED now, there's barely room to maneuver in there now and believe it or not, it's really clean and organized, i just have too much stuff.
Anyways, i pulled the trigger. I'm not 100% thrilled with them, I do wish that I could afford a REAL jig table like a Bluco or even the JMR table but i'm not ******** enough for one nor would I have the room if I could afford it. The Nomads works fine, haven't really had any issues with them. The adjustable height is amazingly useful for comfort and the fact that it's portable and small is nice too. Instead of having to move the part around and reclamping it so u can access different parts of it, you, yourself, can move around the table and just keep the part clamped. The table works well with stand F-Clamps (I bought a bunch from HFT). I mig weld on my table (more heat and spatter than tig) and they are holding up just fine. Every now and then I go get some spatter that I have to grind off though and I keep a sanding sponge close by to "clean" the table top. The holes/grills are also nice since it lets the argon sink down instead of just floating around on a solid table.
Picture below is when i first got them, I had to assemble them in the kitchen since I didn't really have a whole lot of room in the garage.
Oh, and as small as the top might be in specs, it's really not that small, so far i've yet to actually use all 3 attached together, I've only used one at a time.
