Spro McSticks and McRips work well and you can get them for 11.50 - 12.50 at the web tackle shops, best thing to do is put them on your list for when they have those 10-15% sales and you can get them for less than $10.
Academy has some really inexpensive ones - $3.99, but you may have to do some tweaking such as adding suspend dots to get them to suspend correctly. A buddy of mine has done well fishing them.
River2sea has come out with a $6.99 lure, Suspend minnow is the name I believe, it's a deeper diver, 5-7 feet. I used one for the first time Friday in the baby bass color and picked up a few fish on it, had good action and suspended well, not bad for $6.99.
