I have had great luck with Lance Ellsworth, Stepping Stone, Brad Hook, Matt Lautner, and some ABS reps, They are salesmen, they are trying hard to earn your business. I have also dealt with Kirk Roecker, even though he is not really a distributor, he will go the extra mile to help you out.
I don't know about every one else, but when I buy semen from the peddlers, I feel that it rude that they don't come around in the fall sale season to have a courtesy call. I don't expect them to stop at sale season if I only get a rack or two, But, I generally buy up to 300 units a year and have sure found out who I will support in the future. I don't expect any bids, just a cortesy call.
I'm ranting tonight , I apoligize, I'll get off here now ;D ;D ;D
