Of course you should!
As you know, owning and flying in the US is great. Get a capable machine, though, with the long distances. Just ferrying back from Cali means you'll have to hit both the Sierra Nevadas and the Rocky Mountains and there's no way to get around them much lower than 10.000ft, even way down south. If you can afford something a little bigger and faster, maybe an odd type so as to save a bit of money, you should probably think about it. Not that there's anything wrong with a 150 - I love those little aircraft. Gentle and forgiving. Just not the best cross country aircraft.
Just in case, an old Bonanza is not much more than a high spec 152. An old Mooney neither. Grumman AA5? Musketeer?

Or if you're high wing - Cardinal, 172 or 175? Lark?
It's a nice problem to have
