To me it's a no brainer, I like the WS 1098. If you have the extra scratch, get the TRX-2.
Exactly. I just purchased the TRX-1 a week and a half ago and went thru the same "should I" question with the 1098. Three things made me select the TRX over the 1098:
1. I'm lucky enough to have the extra $100 cost not be an issue. Besides that, remember this is a long term purchase item, it's not likely you will only use it 2 months or something. If your like me and most users, you will have it a couple years at the very least. Divide the extra 100 beans into a couple years and it is really pennies.
2. The TRX has more memory in it. This will allow it to be upgraded in the future with more features, more new systems possibly, enhancements... The 1098 is probably about done. So if you get the 1098, and the trx gets a new feature the 1098 doesn't get, you will likely be bummed out. Then have to upgrade to the TRX, and now add up what that will cost you! Much more than the 100 difference.
3. The TRX likely has a slightly faster processor being it's a newer unit/design and can handle the newer systems. So why wouldn't your go for the best....
Unless the extra $$ is a real issue, go for the TRX.
