Dont feel too weird, it just came out a few months ago.
I have the UX2.
For the money, I think it's a very solid value. $199 for a USB audio interface that does 96khz, has 2 mic pres with phantom power, has a normal and padded guitar input, models bass, mic pres, and guitar, can be expanded with model packs, has a dedicated studio monitor volume knob as well as dedicated headphone knob, you really get a lot in one package. Also has SPDIF i/o as well as stereo line inputs and 2 TRS jacks for footswitches that can control your DAW start/stop etc.
Bear in mind that it is 100% reliant on your CPU to do all processing, there is no internal brain whatsoever. So... you do need quite a beefy PC and must have XP with SP2 for your OS if you are a PC user.
If you are not expecting the world of the thing, and know in advance that you will have to tweak the shit out of it with various plugins to get guitars sounding 80% or so satisfactory, the I say go for it.
The other option is to buy a podxt, and an interface. $300 for XT and $200 for basic firewire/usb interface, so...
Again, I think it is a really freaking great value for the money, but the tones are nothing to write home about. That's not to say that it sounds BAD, it sounds like a POD. It is more than enough to do home demo work, and it works very well for me with 15 or so tracks in Sonar5 at 96khz/24bit with 5ms latency.
The direct monitoring is also zero latency, and its nice to be able to track leads that print dry but you can monitor wet (lil' verb n delay for some shreddy vibe).
I like mine... It's not PRO, but its not meant to be. For all that it does, and for what it costs, it is a no brainer.
