K-Line's White Super K Track

So far, I've only been able to locate 42" diameter curves, 10" straights, and 90 degree crossings.  I'm looking for more curves (42" or any other diameter they may have made), more straights, switches (left and right) if they were ever made, and 45 degree crossings (if they were ever made).  I'm not a rich man, so please contact me only if you are asking reasonable prices for each---not inflated "collector" prices.  My e-mail address is in my profile.
