Pink can be overdone.I agree.
I like the deep pinks but I have yet to see a really dark purple.
Just my guess but I had heard about Michigan Bulb also.
All bulbs come from the Netherlands and the price must be according to grade of bulb, so the smaller bulbs are cheap for website companies to buy and resell.
Personally I dont have 4 years to wait for small less expensive a lily to mature.
Guess it comes down to personal preference.
