I'm sure this has been asked before but I'm trying to figure out which program to ask for for Christmas.

I have a fairly substantial collection of perhaps 50,000 coins. I have been hand transferring it every few years to the most current Red Book to get an idea of it's worth as well as to take with me to coin shows.
This, of course, creates huge opportunity for human error each time I transfer the information.
I tried one brand of software a few years ago which I worked on for many hours before having it ultimately and repeatedly lock up on me.
I want one which:
Easy/quick to enter (perhaps mulitple) coins and rolls of coins.
Is Very stable and capable of handling a collection of my size.
Includes Canadian coin option
Automatic "purchasable" updates annually
Allows for purchace price of coins to be included in record.
Will spend up to $2-300+.
Easily customise reports
And did I mention easy/quick to enter?

It seems like most of the many I have found do most all these things except I am struggling to understand the differences.
Is there one which is known to be the best?
What do you all think?
