I have the OV-10A partially built, but just awaiting a different project to complete before I carry on, and an F-86K in 32nd, the 2 Seasprites, a Dauphin, a Huey, a Jaguar and a Super Etendard in 48th. The OV-10 is decent, but require some work, and I hear the the F-86 requires patience and close scrutiny as not all instructions are correct. The kits are very nice in look but the 48th kits are very detail heavy and have what I consider unnecessary detailing such as a full engine and transmission on the Dauphin, that looks to be reasonably correct, but extremely fiddly to get to work...
Now with that said, I'm mediochre at best and can only hope to do a decent job, but I'm sure, even though these are not Tamiya by any stretch, anyone can make a fairly decent model out of these with some patience and skill.
I have seen Ernie's build of the T-28, and it looks really well made, so I believe from what I have gleaned from other fora, that it is a superb kit.
Cheers and pardon the long waffling!
