I waivered back and forth between the two. I really wanted a stand up machine so that I didn't have to sandwhich and baste the quilt. However, the price difference was too much. Then, in Paducah I had the chance to try the BlockRockit which met my needs (standup midarm with a ten foot frame) and my budget for around $5000. I have had it two years and am still very happy. If you call the owner, Lynn Barlow, tell him Kaye Hlavaty sent you! He interacts very well with his owners. I called several times in the first few months with issues that were resolved with just a phone call.
Feel free to PM me for more information.
