Shit mate - any bike shop can get you a rear swingarm stand - the only possible issue on the 250 may be that the swingarm is too narrow for the generic stands. Most are adjustable in width.
Pop onto the phone in your area - do a ring around find who has one at a decent price (around $100-$150) and ride over to try it out.
Also there is a chap trading on Trademe often who sells excellent ones for $65 plus shipping. Goes under the name of Houseofcustoms I think.
Some on TM now by other sellers:
