The ad says the finish is ruby red strata. Here's a better shot, it really is a nice finish.
Yes, it does look like Purple Grain Pearl. The Tempro line was built by Pearl, so can be considered a Pearl drum kit. The lugs are of the better "battleship" style and are great lugs.
Is the sale only for the 3 drums, or is a snare drum included? The addition of any extra cymbals, or non-original hardware, should not be a factor in the price.
