Another piece of advice RE Amazon:
Setup an account, do some browsing and put everything that you might want on your "Wish List". Don't purchase right away.
Give it about two weeks, and pull up your wish list whenever you get a chance. You'll notice that Amazon is constantly changing their prices. I've seen items on my wish list go from $120 one day to $88 the next day. Some prices don't change very much, but some of them swing around a lot.
Obviously, you should buy when you see that the price is right. I've scored some awesome deals doing it that way.
RE what you should buy.... hmmmm.....
On my list I have in channel visors, an MV-50 air compressor, blue sea fuse block, powered subwoofer, CO trail guide, transmission coolers, tire repair kits, etc. Theres alot you could get with $175.
