What Opeth CD should I buy?

Orchid and Morningrise are very different from the rest, though MAYH is still quite different to BWP and Still Life.

Get Morningrise
Then Orchid
Then MAYH
 
The bonus tracks don't fit in with the rest of the album. They are nothing but rather bad, old songs, which have nothing to do with the album. The production is totally different, too.

They don't have the Cd's without the bonustracks on Cdon.com...
 
The above is only my personal preference.

Of course it doesn't hurt to have the bonus tracks! One can never have too much Opeth, right? ;)
