What controller for company

I have had the same palmer economy controllers for over 10 years, 2, 45 ohm, and 2, 25 ohm that I use when company come over. I rewired them right away and they have been repaired a number of times, two are no longer repairable and a third is giveing me trouble. I have a defalco and a PM that I use for club racing, and personal use. I would like to get new ones but am not sure what. I don't have alot to spend, (about $50.00 each)but I do want good response. I run stock motor on a wood road course with variable power, SCC wiring and drver stations with XLR connectors. What would you recommend.
Thanks for the help
