At one time I was frustraited with the lack of weller support by my LHS on irons. We do have an excellent HS in my area too. I ended up burning up my heating element and was forced each time to buy a newer model.
Now with Action I just buy the heater element and a few tips per order. I even bought the Iron Temp controller for $32. You can plug in any iron and regulate the output or turn it down to save the tip. It even has an on off switch.
I would not go cheap like radioshack. You get what you pay for and they don't have decent tips.
If you buy an iron make sure you can get part support.......
