Anyone knowledgeable on air compressors?

[ScrapMetal]

I could really use the opinion of someone who is familiar with compressors...

I have  been trying to determine what kind of air compressor I should replace the "old time bomb" with.   I've done quite a bit of reading but have seen a lot of conflicting information 1-stage, 2-stage, dry, oil, rotary, piston, etc. etc.

I am thinking a 30-40 gallon would be the biggest I would want in my cramped little shop (old compressor is a 30 gal.).  It would be nice to have something a little easier on the ears as well even though I do wear hearing protection.

Now, earlier today I got an e-mail from Eastwood introducing a new product, a scroll compressor: Compressor

I tend to take advertising with a huge grain of salt but this thing sounds like a dream come true (except for the price).  My question is basically, could this thing be just as good as they say or are they being misleading?

Thanks guys,
