I've recently stepped up to a DLSR (canon rebel w/18-55mm lense).

Previous cameras were all point and shoot - last one was a olympus c730.

Anyhow, I like to do outdoor night photography mostly. I'm a causal photographer...
something I do maybe a few times a month tops.

I need a recommendation for a decent telephoto lense - something like 70-200mm
range and under say $300. I don't do enough shooting at this point to drop another
grand on a lense - if I find I get in to it more, I've got no problem spending the money
however.

I'm thinking about a lense thats a f2.8 with the above specs.. mostly because I think
it'll help my night shooting more so then the usual 3.8-5.6 telephotos.

Any suggestions as to brand or specs would be greatly appreciated.

Here's a link to a recent shot with my c730 of the santa monica sky line (show from malibu) to give you an idea of the shooting I like to do:
