Which Boss (RC-10R or RC-500) do I Want/Need

[tommyga]

I play 90% Solo Gigs. I've been using an Alesis SR-16 for 15 years, and have recently gotten an SR18..but I'm still not comfortable with it yet. I have finally decided that just the Vocal, Guitar, and a Drum Beat isn't what I want anymore. What I want to do is have the beat, overdub a Bass Line, and on a few songs..maybe add another Guitar here and there. I'm hoping that you guys can help me decide which one to pick up. A few things I have noticed are;
RC-10 has many more Drum Patterns, so that is a plus there.
But the RC-500 has much more memory, so you can probably have 100 or more songs stored in the unit.
Also..the RC-500 actually tells you the Name of the Song or Pattern ..whereas the RC-10R doesn't seem to have the read out on the Display by name. Am I right?
Thank you very much in advance for your help.
