Is it worth it?

[tdwp117]

I recently read some reviews on my bd player i bought about 2.5 years ago, and i realized it was not just me, the upscaling sucks on it. (by the way by bd player is a sony bdp-s350). I'm thinking of buying either a Pioneer Elite dv-46av or a Pioneer Elite dv-49av to upscale dvds. I only own about 20 dvds or so of which only 12 i really watch. however i watch about 1-2 movies from netflix every week on dvd on my bd player and the pq is starting to become painful. im just wondering if any of you guys think i should buy one of these players if i can get one for under $100 (i see them on ebay for like $50) or if anyone has any suggestions on other good upscalers for about the same price or a review on one of the ones i'm considering buying.
thanks for the help,
