I personally think you have plenty of material, unless you've perfected everything you wish to learn from the things you listed.
Advice::Save the money. You don't have to put it into a savings account. Just put it away somewhere. Save it until something catches your eye. Don't ask for input. Just browse magic sites and product reviews until you find something you think you really want.
Wait and see what is put out by the bigger magic sites just in time for the holidays, penguin magic usually does tons of specials for the holidays.
Two cents...and I felt like being different, I've felt very run of the mill lately.
