Dep. on the E-11 blaster you intend to build, you need either a M38 or a M40 variant...
Both seem to fetch quite a dollar, if the right people watched the same auction. I found that $100 - $150 is the absolute max. for them with the M19/ M32 being significantly higher (see my above post).
$150 isn´t a "bargain" for a correct M38 IMHO, you must be lucky to fins a person who is willing to pay much more for it.
I´m in the same boat for the other scopes...
- Have enough M19/ M32´s for all blasters I´ll ever build
- Have enough M38/M40 for my current and future blaster projects
- Have enough Single Points (all kind of variants)
...
- DO NOT have enough ASI and/ or Model 7 scopes :cry
