Searching Completed Auction Software or Website?

[thewhit]

I was wondering, is there any good research tools (software or websites) for checking completed auctions and their sold price from sites like ebay or amazon?

I use Market Place Research on my desktop (allows me to search 90 days of auctions) but I have not found anything that works well with my xv6700.

Any suggestions of good or bad software or sites?

thanx
