I'm not sure what you are really wanting. Something for use only in your home so that the sewing area is flush with the rest of t he surface ... or ... something to take with you. I am guessing at the first one.
If $ is a concern and you don't want a cabinet where you can lower the machine when not in use, then miss_ticky2 has a good idea. Use an old table or desk and have someone cut out an area for you machine and build a lower shelf to place you machine. You can get a local plastic company to make you an inset if you want [we have a great one here in Phoenix.] With this you can set the size of the table/desk you want to use.
You could also buy a large extention table to fit your machine then use an adjustable Lifetime table for your base or a table/desk.
It all depends on the amount of $ you want to spend, the space you have, and the size quilts you make.
At the end of our annual Quilt, Sew, & Craft Show down here the vendors sell their cabinets for a discount.
I prefer my Horne cabinet because I have a 2 bedroom townhome and need the room. I can put an adjustable Lifetime table at the back end if I am working on a larger project and another on the side by me. I like that I can put my machine away when company comes. This esp since my studio [2nd bedroom] and a HQ16 in it as well as my sewing/quilting stuff.
