Product Compare: Tom Rapid C-80 v. ZooMed 501

Anyone using either of these guys care to chime in with an evaluation? Just did some good research on them.

Tom Rapid C80 - up to 20g - 19.99 - Big Als
ZooMed 501 - up to 30g - 37.99 - Big Als

Prices vary from place to place of course..PetCo was near 50 for the ZooMed. wouch!

anyway...would like to hear from anyone out here using either or has experience with either.

Thx.

Holy Cow! I found myself at Petsmart this afternoon I noticed that they had a ZooMed on the clearance rack (missing brackets). Then I noticed the price.....$55!! wowsers! I asked about price matching but no one could answer. Will call shortly and speak to a mgr.
