I bought one of these a number of years ago for my old Welcraft walkaround 23' I think I paid $240 for it? It lasted me three seasons. Fit it once, shrink it then remove it in the spring. If you reinstall the supports the way you had it the first time it will come out close to the original install. Nice thing you are not throwing it away like you would with a regular shrink job. I would buy a roll of tape from wherever you buy shrink wrap stuff and you should be good to go. You can vent it if you want, and it's plastic so the snow slides right off.
Or you can do the tarp which is economical but depending on the bride you may be limited to the "look" of it which may be unpleasant.
