If you really like the CRF250L, I say go for that.
Honda does still make the 230, just not the "L" street legal model anymore, the CRF250L took its' place, they are about the same size.
Should be able to find one on the used market, or even a brand new left over at a dealer.
Here is nearly new one in Boise, $3500

Another with only 1800 miles, $2800

Side note: It really drives me nuts that Honda changed the name of the XR's to "CRF"...the "CR-" tag was for their
race bikes, and XR was for their casual trail bikes. It gets confusing when someone says
CRF250...I automatically think
of the race bike. Damn you Honda!
Anywho...
As for the no kick starter thing, if you keep an eye on the battery you should be ok, buy a trickle charger to keep the battery charged up.
My e-start only 505, stranded me a couple times in some hole in the back country, we got it started again, but it was a pain. (I was being lazy
about battery maintenance tho')
Funny thing, my Gasser has an e-start but I rarely even use it.
