My Dremel finally Died for good!!!!!

[dabears]

So last night i was cutting and working on my fenders and my 7y/o dremmel finally died for good!!! Inside the dremmel there is a spring that attatches the motor to the spindle and it shattered in pieces! Last week it started making a skipping sound so i tore it apart and rebent the spring to work as the tab gad broken. Well now its done for and i cant find the replacement part...... So now instead of buying my scroll saw i have to go buy a new dremel. I know a lot of you use them so which one is the best one? there are at least 4 or 4 models now and im not sure which one to get? WOuld love to hear your ideas and thoughts as to the different ups and downs of the models you have.... Thanks!!
