I was able to test drive the Innova at the Dallas Quilt Show last year, so if you have quilt shows near you, definitely check them out. There were probably a dozen manufacturers of long arms at the Dallas Show, but Innova was the only one with the M bobbin at the time which was anywhere in my budget universe, so that was the only one I cared to try at the time.
When I later saw the Homesteader, it had the big bobbin, the deeper 22" arm PLUS it takes regular sewing machine needles, so that's what moved it to the top of my wish list.
It also has a reputation for having a very responsive-feeling carriage system and it costs less than the Innova, which was already reasonable, IMO. It's still on my short list - if the Homesteader turned out to be a disappointment, the Innova would be my second choice. But I'd probably have to wait and find a used one.
There are dealers for the various brands of longarms spread all over the country. Ask at your LQS or post a query on craigslist to find them. Some of them operate from their own homes.
Remember that the person who is showing you their long arm machine is getting a commission and the adherence to this brand or that brand approaches a fervor that is nearly religious. (just kidding, just kidding!) Ask lots of questions and remember that any dealer will want to downplay and minimize a particular machine's shortcomings and showcase its strengths. (that's what dealers of anything do, right? That's their job - to sell you a machine.
)
I'm not criticizing dealers at ALL in any way, here - I'm just saying that the
shopper should not necessarily buy the first machine they test drive just because the seller is so nice or because they can quilt so easily with their machine. The shopper should try to get a good long trial with the machine so that they really have a feel for how the carriage behaves at various speeds.
