In the US, $1k should get you a descent set of gear. Not the best, but also far from the cheapest.
Helmet $350 should get you a nice shoei.
Pants can be had for $250
Thats a total of $1150 Depending where you buy from, or wether you are willing to buy last years models, you can knock that down to say $800.
If you go to textiles, you can sagnificantly reduce that even more.
