Trade: Nikon SLR and Lenses for MF or LF Camera

[RedSun]

All Nikons are in mind conditions, never in professional use:

F5, boxed
F100, boxed, MB-15 optional
N90s
SB-28, not eager to part away

AF 28-70/F3.5-4.5D
AF 28-105/F3.5-4.5D, in box
AF 28-200/F3.5-5.6D, in box
AF 70-200/F4-5.6D
AF 70-200/F4-5.6
AF 75-300/F4.5-5.6

Interested in Mamiya 645 manual, RB/RZ67, Bronicas, and Hasselblad (old 5xx). Just want something very basic (<$500 range). But just let me know and I'll consider each offer. Thanks.
