SQL: to convert or not to convert

[teddyFBI]

I'm somewhat tech-savvy, but this SQL thing is beyond my level of understanding, and I'd be very appreciative if someone with more tech knowledge than me could post an informative post laying out the pros and cons of converting one's PT DB to SQL. From my limited knowledge, all I understand is that it would make everything -- from importing to viewing stats -- run much quicker. It would also remove the 2 gig max size of Access DBs.

But what (if any) are the downsides?
- does it require a lot of tech knowledge to convert?
- do HUDs (specifically PAHUD) work with SQL format PT DBs?
- any other drawbacks?
