If you could get lucky and find one cheap, this Tamron would be a lens to consider.

.........something to think about if you shoot a lot of low light stuff, the better high ISO performance of the K20 or K7 CMOS sensor gives you more latitude shooting slower lenses in lower light situations. Your A70-210/4 would shine with either of these bodies at higher ISO without having the size/weight penalty of the faster glass.
A last option would be to just bump the ISO up another stop and look for a good NR program. I'd take a close look at Topaz Denoise. It's kinda slow, but does a remarkable job reducing noise while retaining finer detail.

All excellent suggestions snostorm...
1. I considered the 80-200 f2.8 but I know that they're heavy since I've used the Nikon 80-200 AF 2.8 before. I also know that I'd use it more @ 200. Although price wise they are competitive, knowing that I'd use it 200 mostly, I prefer to opt to wait for a 200/f2.5 or as I stated above possibly a Nikkor 180/2.8. I'd still consider it, if one comes at a bargain price
2. ISO performance either through another body or as I mentioned, through sensor evolution is another option, one that will have to wait. I'd rather spend the money at this moment on good glass
In the end, I opted for an AF lens. Once I have the time to look through my "test" shots, I'll let you guys know my thoughts/impressions. I will still keep an eye out for one of these: MF 80-200/2.8, 200/2.5, 180/2.8 or 200/2.8, even though I have gone ahead and purchased the 55-300.
