What do you use instead of Yahoo backlinks Checker?

[Dazed]

Since yahoo closed its backlinks checker tool, what do you use now?

It was my number 1 factor for buying links.

bing, alexa, ahrefs

Open Site Explorer, works perfectly.

Blekko (seo spyglass has it implemented)

There are also MajesticSEO and Sistrix, really depends a lot on your personal taste and none delivers perfect results. Well, YSE was far from perfect, too, but there isn't a really good free option any more if you want to see more than a few links.
