For a long time I used a Minolta Autometer IVF with the 5degree spot attachment. I always found it to be accurate, and my only two complaints were that it was a P.I.T.A. to switch from incident to spot modes, and the spot was not all that tight.
I shoot almost exclusively in available light - I don't think that I have ever actually used the flash mode of the meter.
I now carry a Pentax Digital Spotmeter as well, which has the tighter spot, and I feel that I have the best of both worlds.
If on a budget, you can certainly get away with the Minolta Flashmeter IVF, and the spot attachment, and if the spot really bothers you, add another dedicated spot meter later.
