You want brutal honestly. Do an ebay search of completed auctions for Mathews Drenalin bows on ebay. Only looking at Mathews drenalin bows that either had bids that did not meet reserve or sold it looks like ones with various accessories are averaging about $400. Some bare ones sold much lower than that. A lot may depend on year made. I do not know how many years they were made or if they are still being made. Those prices may be for very old bows for all I know.

Yes, too much. The accessories won't increase value as much as you paid for them. A used bow is like a used car with quite a bit of depreciation. I would think start out asking maybe $600 and be prepared to go lower.
Consider selling bare bow and splitting accessories. May help it sell since most people plan to add accessories to their personal taste, and also selling itemized may give you a higher total profit. Depending on length, I would possibly be interested in the gold tip arrows.
