colnago62, you mention wanting to save money on the frame purchase. I'm not familiar with what kit you already have as well as other thing. But, the track frame ranks very low on the benefit/cost scale of things you can throw money at.
Unless you are looking for a new frame to avoid a problem you have with your current frame (e.g. wrong size, slipping seatpost, slipping track ends, etc...), there is a long list of things that will very likely show measurable gains before a new track frame will.
Maybe think of the frame as "fine tuning" your system after you've taken care of some of the things higher on the benefit/cost scale.
For example:
(Assuming all frames have the same size/geometry and all other components)
Setup A:
Steel frame + Zipp 808 race Wheelset
Setup B:
Cervelo T4 + 28 spoke training Wheelset
Setup C:
Felt TK FRD + 28 spoke training Wheelset
Setup D:
LOOK R96 + 28 spoke training Wheelset
You would be measurably faster on Setup A. Meaning, if you did sprint or endurance time trials the same day using all 4 setups, Setup A would be fastest.
