I've used some of the Back to Basix ones. They are very nice. I used them on my Harrier and Stoner Hawk as well as some other projects.

I received my Fenris bases on Saturday. It took a little over a week to get here - which is awesome , considering they had to come across the pond.

They are very nice quality and the bottoms seem to be very level. I will get some pictures up, but really, these are cast very nicely and fairly flawless.

Cool.

As I said earlier I didn't want anyone to be put off Fenris by my earlier comments. Fenris offer excellent value (in my view), a nice breadth of bases within their sets, speedy and friendly service. I have used lots of their bases already (and will use more). I look at a few different areas and only in one or two (albeit minor) areas do a couple of other manufacturers come out ahead.
