If you have a Micro Center near you they seem to have the
best deal available but this may have already expired 5/19 or may expire 6/2.
The next best deal are the CostCo NiMH's you mentioned. CostCo B&M is selling all this for only $25 - $5 MIR = $20 final price:
Panasonic 5 hour charger
6 1600 mAH AA batteries
2 AAA batteries
2 C & 2 D size adapters
If you want the ultimate in NiMH rechargeable batteries get 1800 mAH's from
Thomas-Distributing.com or
SunnBattery.com (do a CTRL F and search for 1800 mAH). The best deal is a combo package like
this which includes 8 AA 1800 mAH Gold Peak NiMH rechargeable batteries, the top rated MAHA 204F quick charger and car adapter all for only $39.95 plus shipping/handling.
I bought the Panasonic NiMH's from CostCo and I've been very pleased so far. IMHO the additional $25 isn't worth it for the 1800 mAH's unless you need absolutely the best batteries/charger. The difference is barely noticeable between 1600 and 1800 but the MAHA 204F charger is awesome. Used to have one until I sold it to my sister.
Disclaimer: I don't work for Micro Center, CostCo, Panasonic, Thomas-Distributing or SunnBattery. Some idiot in a previous thread assumed I worked for SunnBattery, just thought I'd clear the air this time.
edit: I just copied that from the Vivitar Hot Deals thread I posted in. I think the Micro Center deal is dead. The best bang for your buck are the Panasonic 1600 mAH's for $20 from CostCo B&M or from SunnBattery or Thomas Distributing. If you want the best get 1800 mAH's
