Hi Leslie

It is hard to tell from available facts.
A full
new 10" SW can be had for $899 (with warranty)
As the add says "
TUBE ONLY" , does this include the finder scope? ($100 to buy separately)
The two standard eyepieces (Super Plossl 25mm and 10mm) to buy separately would be about $70RRP (but can be had for about half that).
CHECK: Hopefully the two tensioning handles are included for Alt friction adjustment.
Also check that the two eyepiece adapters (hopefully) are included (1.25" and 2")
Tough decision, but the SW10" is a very good instrument(IMHO)
