Hi, the little grace ll is not a bad frame if u can, get the pro metal carriage upgrade and a speed controller it makes alot of difference. It also only goes up to a queen size and if u get the carriage upgrade u will still only be able to put a machine on with aa throat up to 16" not 18" like on most of the other grace frames. I also had an Inspira. What Inspira frame is it? I had the first one with the pantograph shelf above, it was easy to put together and had a smooth motion with the carriage.it had the speed controller built in but was only for machine that had 3 prong foot peddle like the Janome 1600p. The only draw back was the carriage was set low and gave me back ache. Also it only went into crib or king. I don't know about the other frame u are looking at . I how this helps.
