I couldn't resist at US$219 minus a few holiday gift cards over at Best Buy, but now that I have it at home it is *OBVIOUSLY* not the USM version that is selling online for ~US$190. It is much louder than my 300D's included 18-55mm lens.
I know the 75-300mm Canon is a little slow (f/5.6) on the deep end and is a bit soft on focus after 200mm, but I really wanted the range (especially with the 300D's 1.6x magnification factor) and $200 is my LIMIT (wife-set) on a new zoom.
Question: either way, I'm taking back this lens to Best Buy, but should I go for the same lens at $125 or so (cheapest I've found for the US version online), or go ahead and spend the $200 again but get the USM? Will I be any happier with the autofocus speed or reduced noise level?

I missed it and was going thru 10D withdrawl. LOL!
Freeezing rain yesterday kept everyone indoors and wicked cold today has turned everything into a giant skating rink.
