Useful Dillon Accessories???

[Big joe]

Well, it looks like I talked my beautiful wife into buying me the Dillon 550 for Christmas!!!!!!!!! It will be set up fore 300 Win. I do have 4 other rifle calibers and 3 pistol calibers that I'll be getting conversions for. I noticed the conversions can go anywhere from $45 to about $100. Can someone who use these tell me exactly the usefullness of the full convesion equipment w/ powder measure ect. Also let me know if there are any other useful accessories for the 550 I should consider.

I can't wait to join the ranks of the progressive reloaders!!!

Thanks in advance for your info!!!
