The Wico sticks you mentioned are NOT the chrome handled ones.
They quit making those a long time ago.
I've seen a few blue Wicos, like you are asking about, on ebay in the past couple months, the last of which went for $18.00.
They are few, and far between, though.
Somebody did just buy a whole lot of used joysticks a few weeks ago, that I think included some blue ones.
Those "might" start showing up again on ebay, if you're willing to wait long enough.
Other than that, you've got the T-stik Plus w/ add-on blue balltop handle for $24+14+shipping, and that's about it.
Another option would be to buy a couple red-ball Wico sticks, and replace the sticks with blue ones when you can get some on ebay.
That will at least space the cost out for you.
