Donny,
There are so many choices for players these days it boggles the mind. It seems to me just about any player of any genre can find an Arranger that will fit their needs. I use Dan's Varranger on gigs too and it has many very strong features the best of which is Dan's loyalty to his customers. Right now I am deep into my S950 and like it a lot. I might take another look at the BK-7M in the future.
Yea, I'll be 73 this year - but you never stop learning in life.
