Don't buy online unless you've personally played the digital in a store before.Just don't do it.
When you shop in a bricks-and-mortar store then buy on line to get it cheaper, you have two problems.1. Integrity2. Sooner or later you are part of forcing all the bricks-and-mortar stores out of business.Don't take up their time unless you have intention of buying.
While I will never buy a music instrument online ( or clothing) I will use the online to find the price to negotiate with the brick and mortar. There is a great value to being able to try before you buy so even paying a little more at the brick and mortar is ok since we know what we are getting.
