Re: Direct Recording
As far as GOOD, you'll have to let you ears do the test, if at all possible... Some of the modellers sound impressively real... Others sound VERY digital with a metallic overtone, not in a good way!
The tonelab sounds REALLY good... The tube pre warms things up a bit before it even hits the amp/mixer.... Unfortunately, they weren't on the market when I bought my processor, so I ended up with the Digitech GNX3. The tones are also useful for direct recording and practicing, but not sure how useful it would be for live gigs into a power amp or direct input to the mix...
Also, think about the interface on them... Some of the systems are set up for desktop, so you dial in the tones each time you use them. They usually have a Use Preset, but you have to acces that by twisting as well. The Tonelab, The Digitech GNX series, The PodXT Live, and a few others are setup like a pedalboard for switching on the fly. A handy feature whether playing live or just farting around on the PC.
Also, look at the ouputs... Some have just a headphone/line out where others have multiple sources of output including USB2 and/ or S/PDIF....
Just a few suggestions on the matter... There are small differences that help constitute price differences, so be sure to look under the hood before you buy. The old adage goes, Ya get what ya pay for..
Good Luck on the purchase,
