[quote name='fatback' post='656867' date='Nov 17 2009, 12:12 PM']If you want punch, you need a compressor. You shouldn't really hear a limiter most of the time.
I keep singing the praises of the Trace elliot SMX dual compressor. It's a gem and can be as subtle or as effecty as you want. Also has an amazingly useful tone control, mixing the two channels. You should easily get one for £80-100 on the bay. Got mine for £80 a few months ago.
Watever compressor you get, get a dual band one though. You really need that control.

I really like the TE SMX compressor (the preamp one, rather than the pedal), but I'd say it's designed to be 'seamless' rather than 'punchy' (depending on your definition of 'punchy' - it can vary a lot!). I'd also refute the necessity of using a [i]dual band[/i] compressor, having once been convinced of that by the TE manual myself. If you want to use compression as an effect rather than for levelling and sustain, you might like to try something with more options, like the dbx 266XL - a model that frequents the for sale section at quite reasonable prices. Having never tried one, I can't actually recommend it as a unit, but I'm guessing it's the kind of thing you want to go for.
As an aside, do make sure you're not actually trying to achieve the 'punchy' sound that is a kick drum and bass guitar played together on record/over a PA when you're playing the bass by yourself - you'll be searching for the right compressor forever!
