The kickpad is okay if you want to get a decent kick sound quickly (like for a live situation, with someone who can't engineer worth a sh!t).
I use a D6 Audix (sometimes a D112 AKG) for recording and move the mic around until I find what sounds best to my ears (usually about 4-5 inches inside the resonance head port-hole, pointed off axis at the beater). Then I use maybe two bands of subtractive eq to cut what I don't need, and compress about 2:1 to tape and in mix (using a DBX 160A lately). This kills any sound I've ever gotten with a kickpad, and it doesn't take very long to get.
Say you spend about $100 on a kick pad to use with some dynamic mic that may or may not be intended for a kick drum or bass rig. You're already half way to an excellent kick mic (~ $200 for a D112, D6) and about a third (~$300) to a EV RE-20 (if that's your sound). Or, buy a new/used ATM 25 (or Pro 25) for $50 (you'd be surprised how good these little mics sound, even on guitar) and mess around with mic placement. Eq and compress to taste. You'll find a sound that you love (one that's reproducible, referencing a few notes in your mix ledger) and be money ahead.

BTW: A great drum sound starts with a great drum set and new heads tuned correctly. Recording someone who knows how to play well (and play well in a studio) always helps too!
