Susan - My Husband got me a Schacht 8 harness "Mighty Wolf" folding floor loom as my combination Anniversary/Birthday gift. It is definitely something you have to save for. Mine came out to about $3500. The beauty is, it folds up to lean against a wall for easy storage. It's fairly light weight and once I'm healed up from surgery I could literally probably half lift it and drag it anyplace in the house I wanted to. I could even order in the wheel attachments they sell for it and wheel it anyplace I wanted.
They have smaller version called the "Baby Wolf" and the "Wolf Pup," all of which are shown as being able to fold and fit into a car trunk! Those are also vastly cheaper than my large loom, and if you had no intentions of creating larger pieces, one of those smaller ones would do what you needed. If you have a local weaver's guild I would look into joining up, as the folks there could really give you a lot of insight on what to get for your needs, and help you find used looms someone might be selling, or other used weaving equipment. I recently went looking around and found a Weaver's guild locally I am going to look into for myself.
