A couple of things to look at with that machine. TIG is only rated at 150amps output. That is enough to do a lot of work with but depending what you are looking to do you can start to run out of steam for thicker materials.
It also looks like it is a lift start machine, which means you touch the torch to the work, then lift it up to start the arc. Again nothing wrong with it, but not as nice as a HF non-contact start. If you don't get a clean lift and stick a tungsten most of the time you do the pogo stick routine with arc and stick until you get if off of there, have a bunch of arc marks all over the piece. I think some of it is technique of the lift to get it lit every time without sticking it, but I haven't figured it out yet.
The TIG is also DC which means no aluminum in tig mode.
Personally, I do not like the hand/finger controls and would rather use a pedal even in awkward positions. It is just a matter of preference. The integrated torch control does make for a bulkier torch if you chose not to use it and go with a pedal.
Personally, if it were me I would be looking at these 2 machines instead of that one. This TIG machine is comparable to the one in the multimatic200. It also has some pulse functions, I didn't see that with the multimatic200 but it may have it.

I would then be looking at this machine for MIG which should be comparable to the multimatic200.
http://store.cyberweld.com/milmax140str.html Price for the 2 machines is close to the one but you don't get the spool gun. Again that is just my opinion, I am not sure how I really feel about multi-purpose machines.

The other has been with the old and worn out MIG welder. Never even tried TIG welding. This should be fun. I have yet to have time to even plug in the machine.
