My choices:
Any of the C/KC/RC-135's: AMT did them in 1/72 scale, they can be a bit difficult to find. I believe that Testor's or Italeri reissued the KC-135 kit not too long ago. They have their pros and cons--you may need to add/delete some details to suit your particular aircraft.
C-130's: Testor/Italeri's is best, they do both 1/72 and 1/48. An MC-130E would be a conversion, not sure if there are any available but someone else may know.
A-10A: What time frame? Any of the early Davis-Monthan or Myrtle Beach planes, and I'd go with Tamiya's early kits in 1/48 (ESCAPAC seat, no chaff/flare boxes). Any later, and I'd use Monogram's (currently the kit is in Revell boxes). In 1/72, Hasegawa or Italeri make decent kits. I'm building a Revell (Monogram) kit now, and it has a few fit issues, but nothing a little bit of old fashioned modeling work can't fix. I also built Revell's orignal A-10A (it dates form about the same time as Tamiya's) in 1/48 scale. It also isn't a bad kit, but they have been long out of production. As a friend and I once discussed, the modeling world still needs a good, state-of-the-art A-10A kit...but there are a few that will fill the bill.
F-4's: 1/48th scale, Hasegawa's are better than the others, although Monogram's kits are good, too (raised panel lines and all). 1/72 scale, and you'll also find Hasegawa does the better of the offerings. Revell GmbH also does the long-nose versions, usually in F-4F and RF-4E boxings. If they were to release an F-4C and F-4J based on these molds, they'd have winners.
F-14: Hasegawa, both scales. Fujimi also does a very nice 1/72 scale Tomcat, but they were hard to find for a while--some like it better because it has a better shape to it.
Hope this helps...

Thanks Ralph. I do have a few aircraft kits in my current collection. I have a KC-135A from AMT. I worked on the =R models though when i was stationed in England along with a few occasional -E models. I will see if I can score an -R model on E-Bay.
I have a couple Fujimi 1/72nd F-4 kits along with Hasegawa's 1/48th F-4G Wild Weasel kit. I'm looking for the -E model F-4 that has the Missouri ANG decals with the shark's mouth on the nose.
I have the Academy 1/72nd A-10 and a Monogram 1/48th A-10 so I can see what i can come up with there.
Other kits I have are the 1/72nd AMT B-52H, AC-130U Gunship, Fujimi F-4C/D, A-37 Dragonfly, and the Academy 1/48th F-15E Strike Eagle, and I even have a couple civilian airliner kits.
As you can see, I do have a few kits to choose from, but it's intimidating breaking into them when I'm as inexperienced as I am building these kits. I also have to figure out what's wrong with my airbrush as well so I can at least try to lay down the appropriate paint schemes.
Needless to say, I have a ton to learn and I'll be working slow, that's for sure.
