You owe it to yourself to check out the racks at www.elitefts.com
Everybody has an opinion, and mine is just one of them. It seems like everyone I have spoken to- has found that York equipment is not up to snuff. Look around and see what is out there before you buy. I highly recommend you find a power rack with 1 inch hole spacing. I looked at the York site in your post. I don?t see a model with 1 inch hole spacing. It may not sound like much, but if you are lifting at home, without a spotter, you will be disappointed with anything built with 2 inch spacing.
If your choice is between the York power rack and advanced couch sitting, then your choice is clear. Know this, if you are still lifting in 2 years, you will want to step up to the Elite model. Sooner or later, you will trade up.
Top of the line equipment lasts a lifetime and is worth the investment.
Just my 2 cents.
