Sorry, but totally unsuitable, not long enough, not stable enough, won't take the weight.How about something like this, attached to one of your lightstands?

Back to the orginal question, IMO it's worth paying more for something that will last for more than 5 minutes and that will safely take the weight. A lot of these Ebay cheapies are only designed to be used with "non woven fabric" which weighs virtually nothing because it's crap - if you're planning to use paper or, even worse, vinyl, then you need a very rigid structure.
