Busy season! I should get back to the workshops soon enough, but school's starting to get hot. But here:
http://www.pigpenpoetry.com/showthread.php?tid=7500 - Just read through the poems here. Some you'll like, a lot you'll love; that's how I got through all this, at least. Introduced me to Louise Gluck, this thread, and she's pretty great, and now I think "The Wild Iris" is my favorite book of poetry ever.
http://www.pigpenpoetry.com/forumdisplay.php?fid=64 - Also a good place to get introduced to peeps.
http://www.pigpenpoetry.com/forumdisplay.php?fid=68 - This too.
http://www.pigpenpoetry.com/forumdisplay.php?fid=46 - And this.
Now, answering your question more specifically, I'm not too familiar with Bukowski, but I'm finding it a good rule of thumb to radiate outward (that is, start with the most popular, most formal, most classical stuff, then inch your way to the less conventional) and to try as many flavors as you can (thus all the threads above). If no one ever manages to give you a good enough answer there, just reading on will eventually lead you down the right path.
But Gluck (ahem, u with an umlaut) is great. The Wild Iris, that is great. And right now I'm a bit obsessed with TS Elliot, but I'm not sure that's the thing you're looking for.

No one's despair is like my despair--
You have no place in this garden
thinking such things, producing
the tiresome outward signs; the man
pointedly weeding an entire forest,
the woman limping, refusing to change clothes
or wash her hair.
Do you suppose I care
if you speak to one another?
But I mean you to know
I expected better of two creatures
who were given minds: if not
that you would actually care for each other
at least that you would understand
grief is distributed
between you, among all your kind, for me
to know you, as deep blue
marks the wild scilla, white
the wood violet.
