I recently purchased a Panasonic FZ20 at Compuplus for $479.99, a Mack 5 year warranty for $25.99, and a non OEM battery for $29.95. The purchasing experience was without problem, everything in stock and shipped timely. I noticed Mack 5-year warranties costing up to $250 from other dealers, but figured for $25.99 it was worth it. The only problem I have noticed is the battery only lasts about 70% as long as the Panasonic.
