Recommendations Of Stamp Auctions - For Smaller Budgets

In addition to purchases from dealers, I have acquired some stamps (and in some cases, collections of stamps) in on-line auctions. Some have been run by stamp dealers, and others have been ebay auctions. I have generally been satisfied with the results of the auctions, and feel like I have been treated fairly (even when I didn't have the highest bid). But I have only looked at a couple of auction sites, and I know there are more out there.
Do the members of this community have any recommendations with respect to online auctions for collectors with smaller budgets? (Would the answer be different for collectors with larger budgets???) There may be sites that I'm simply not aware of. Also, are there auction sites or practices that newer collectors should look out for?
Thank you all in advance for any recommendations.

I highly recommend Modern Stamps on Stamp Auction Network for inexpensive stamps. What areas are you interested in?

Also Dutch Country.
