Actually application does make a difference.
Like the difference between Logan and C+H (or Feltcher, etc . .) . Sure there are some professionals that swear by the Logan, but many regard it as a hobbyist, or entry level machine. (I can sense this statement will upset some people)
Application (hobby vs. pro or semi-pro) also makes a diff's in justification of expense. For example: While the CH Oval Master may be a good machine, if you are a hobbyist,it may be more machine than you truly need. A mean green gene machine may be better. Or the thingy from Bob at Cornersotne OvalArt.

may be better, depending upon intended application.
6 lbs compared to 60 (or more).
For that matter, with more info about potential use, a CMC for oval (and square) mats could be an unexplored option.
As a general rule of thumb, the more clear you are about your use and application, the better suited the advice will be toward the product or products in question.
Just some helpful unsolicited advice to get better results for our fledgling grumbler.
We now return you to our regularly scheduled post.
Thanks.
