First of all, I have never seen a portable hoop that was worth a ****. Tell the Mrs that an in-ground can be used to hold up decorations for parties, so it will be great for entertaining.
I have a Lifetime in-ground hoop that must be pushing 15 year old now. It's been very solid for me for a long time, quality product, and it was like $200. I moved it once when I put in a new garage and had to pour some addl concrete. It takes a little patience to install, but if you can use a wrench and have an extra pair of hands it is not complicated.
A couple small parts do rust over time, and the backboard had to be replaced when it was shattered (cracked due to kid shooting it w/ BB gun). But very strong value for money. I always thought the "big name" brands over $1,000 were ridiculous for a bball hoop.
Adjustable height 48" model for <$300 now.
