Congrats Antje.
You will be happy with that lovely gear
I've has a Hassy 503 CXI and Pentax NII, and I sold it all, 10 month ago for purchase a Canon 5D and lens.
In October my stomach had butterflys flying inside, I can't live without my Hassy, What can I do? I thought, well, I buy a Hassel 2nd hand kit... but after looking for good prices, nothing, here in Spain, nothing for good money, example: 501 CM whith 80 2.8 Cf and a 12 back, 2000€ in 8 condition of 10
In other words, I took my credit card and purchase a new 501 CM with 80 2.8 Cfe and one 2nd back, I have paid all this gear in "comfortable" installments, for the next three years.
This is my sadly story, sell, lost money and purchase again and gain mental health.
Sorry for my bad English.
