I take it he only has the Jolida.if he has the others and won't let you demo,then I'd go to another.
Your spending a mess of money and you gotta be happy with your purchase.
I did a demo(at home) with a 14000 pre,I wa a little surprised they let me take her home,
I guess they thought there was a chance I'd buy her,there's always a chance.
I'd audition that Jolida for a couple of days,then i'd go to another place and see if you can home demo
All they do is take your credit card#(security's sake)and when you bring her back,your done.
They give you the card receipt back and, NO CHARGE FOR THE DEMO
.I like it.
