Sahara indoor car covers, Any good? Other recommendations?

[jotto]

Hi all,
I need to get an indoor car cover for my C3 Corvette as the garage is very dusty.
Ive seen the Sahara cover ( http://www.carcoverzone.co.uk/sahara-indoor-covers... ) and it looks like it will do the job.

Just wondered if anyone had used this make before and what the fit was like? It looks like they do them for lots of different makes.

Any other recomendations? I want something that wont damage the paint, will keep the dust off and I guess be breathable.
TIA.

Don't know if you've ordered on of these yet, I have just ordered a Voyager Indoor/Outdoor cover. I'll let you know what I think of it when it turns up.
