I am still using the MS Sidewinder FFPro, and I understand your love for it, because I have used one since AWII. It will last a lot longer in AH if you turn the Force Feedback off, and the stick will still feel hefty the way you like it.
The FFPro does have a lack of programmable buttons these days, but a real (and cheaper) alternative to a new stick and pedals is to buy a Saitek Gamer's Keyboard. It has a programmable key pad attached (27 functions) which will really enhance your MS stick. I have been using it together with the MS stick for over a year now, and the two together are a great combo.
I am moving on to a new Saitek stick and pedals now, but the above is an option that you may want to consider... it's a great temporary solution, and it's budget friendly!
Regards
eh?
