Estimating accuracy - mentoring

[MightyJoeOld]

If there is one thing I had to pick from my PM repertoire that I could use more skill and help with I would have to pick estimating. I'm much better at managing a group, keeping projects on schedule, etc. but when it comes down to working on budgets and estimating procured items, etc. I just seem to crumble, not to mention it just grates me in general because I hate the whole estimating end of things (luckily we are moving more towards having a department for that now).

Still, I would like to know if there are any resources you could recommend to better sharpen my estimating skills. Any leads appreciated.

Here are some article about Cost Estimating. Check the EVM article, cost estimating, in my opinion, is easier than activity estimate because the latter suffers of much more unknowns.
