Chris,
most of my pleasure turning has been along this line this year. so I am also a newcomer to it. I have found my radial arm saw to do the best job. giving me gluable joints right from the saw. it helps to try and true up the sides of the blank so it all comes out straight. my best stratagy is to use very large blanks. I tried using a Power miter saw. take it from me it doesn't work. don't know if it is the type of blade in the saw or what but it throws the blank around the shop at the end of the cut. I do not get the same thing from my radial arm saw.
a hand miter saw might work as well. I would also try the band saw using the mitre gauge and the largest blade your saw will accept.
