Bass lines and enhancing drum tracks

I know this should be in the HW section but there is no trafic there and I would like an answer.Plus I am familiar with most of the folks here, so.............Just looking for a small (25 keys) some sort of touch sensitivity and some pads.
All I want to do is play some bass lines for my songs and enhanc the drum tracks with various things. My right hand is pretty comfortable in that respect except I don't have my old controller anymore.
I looked at the M Audip Axiom 25-read good and bad reviews.
I do want a small one though-It will go right in front of my PC keyboard. Top of the line I don't need-the bass lines are the main use.
Thanks for any help
