Personal Trainer Fees?

Ok, so DH is happy for me to have 2 personal training sessions a week. I don't have gym membership but have a treadmill at home and a few other bits to do at home inbetween sessions. I have found a website for a guy which looks like it is what I need... but it is $$$. So, what is a reasonable amount to pay for a PT?

I can go to a local gym and have PT sessions (without being a member of the gym) and pay $64 a session (I assume a session is an hour).

or the guy I am interested in has the following fee structure...

Personal Training

Prepaid:
100 pack @ $69 per session

48 pack @ $79 per session

24 pack @ $84 per session

12 pack @ $89 per session

(48 & 100 packs include a FREE Individually Personalised Eating Plan, added value to you $199)

there is a payment plan for the 100 and 48 session packs but don't know what that it. His sessions are 45 min.

Thoughts anyone?
