Umax,
The answer to your question is yes. I assume you're interested in 1/48 scale? If so, then read on.............
Both manufacturers have excellent quality P-51kits - but Tamiya has more versions - they have the P-51B and the P-51D. There may be others but I haven't seen them.
Hasegawa make a very high quality P-51D. I've got one and I'm not sorry I bought it.
Accurate Miniatures have a whole P-51 family --- (Allison engined) A-36, P-51A, then there's the Merlin engined P-51B and P-51C.
Any one of these kits by any one of these manufacturers is a good buy. You can't go wrong.
Cheers,
