Replying to Buying a Longboard

So last night I got really fucking drunk and went longboarding.  I've done quite a lot of longboarding before (usually drunk), but this time was pretty special.  It was just a super mellow hill to start out with that then got stupidly steep and fast, long story short I got blood all over my tall t, possibly slightly concussed, and pretty in love with longboarding.  So its time to buy one.

I saw that whirling dervish video and totally wanted one of those, but I'm shopping in the $150-$200 range (for a complete) so that probably out.

I heard the kracked skulls m1's are basically a cheap version, but that board looks really thick and stiff to me.  Are they basically just solid?  It seems that way.  I want something pretty flexy and pop-y so I can bounce up and down and fuck around and such, but I'm also 190lbs.  But it just doesn't seem like the M1 would flex period.

What are Bustin boards like?  I was looking at the Complex.  It looks like it would be pretty flexy and fun, and has a cool shape.  The Bustin Strike looks cool too but I think it might be a little short, I'm 6'2 so I was looking for around 42".

I was considering the Earthwin Supercharger as well but somebody told me they don't really have any flex either.

I'm going to pretty much just be either fucking around/carving on slight hills or bombing big hills, I probably won't be using the board to get places because I have a car, so pump-ability isn't a massive issue.  I want something I can do slides with.

Suggestions?  I've really only ridden Sector 9's because thats what everyone has.
