Let me put too you this way you are looking at

$120 for decent clippers.
$30 per blade. You are at least going to need two different lengths. 10 blade and then another length for the body.
$20 for a decent grey hound comb.
$20 for a decent slicker brush.
$50 and up for straight shears
$50 and up for curves

And that is for cheap stuff. So you are looking at a $300 investment at least.

I have several THOUSAND invested and I don't have half of what others do.

Just be careful... I have seen more pet owners hurt their own dogs than not.
