I'm going to try a rack unit to see what I think (don't lecture me, though...I'm still keeping my pedals!). I'm buying used, and a lot of people on here (who don't hate rack gear!) seem to think the Lexicon Intellifex and the Rocktron MPX-1 are solid units that can be found cheap on E-Bay. So, are there any pros/cons that would set one beyond the other? I'm looking for a really solid set of delays, choruses, and modulation effects for spacey, Floyd-inspired music... Thoughts? Also, if you have one of these units used that you are looking to sell (or a comparable unit), let me know. Thanks!
