Why not just use fiberglass? A lot cheaper and it can be removed if needed.

I agree with fiberglass or foam panels and perhaps a sealer. Pocket change vs 350.

I favor foam panels + foam sealant (aerosol cans).
The reason is that the foam will effectively seal the panels as well as the full foam. In a basement the foam sealant will help keep out small rodents (mice). You can double up on the foam to get a full depth insulation.
I've cut the foam on a table saw and it cuts beautifully. A circular saw would work too.
In my area you have to use pressure treated if you are framing below ground. It's probably a good idea anyhow. If leaks have ever been an issue a coat of concrete sealer would be good idea before closing things up.

I agree with using foam sheet as well. As for price of spray foam. That's pretty high. It's usually around $1 BF to have it done and Menards has a 600 BF kit for around $1 BF and some kits are on sale for less than that at times.
We don't have a Menards here however for big purchases it's worth driving from Fort Worth to Wichita,ks... We had to buy our gutter material there because depot wanted 3x as much as menards so it was worth the trip.

I bought a small 2 part kit off of Amazon because my local HD doesn't stock anything. Then I read the instructions. Temperatures required were a bit ridiculous for a basement. I wasn't ready in August, that was my window. This was a cavity where I couldn't get foam board in. The supplied gun wouldn't really work well in this application anyway. So I just used my foam gun, and it seems to have worked fine.
I might end up using the 2 part kit this year, I have some cavities that are a real pain to fit board into. Although in the rest of the basement I just fit multiple pieces together and foamed them and it worked fine.
The stories you hear about failed foam are mostly because the temperature limits aren't followed. I didn't want to screw up and have a difficult cleanup job.
