I'm paying a similar amount for similar traffic, and I do recall it was a bit cheaper when I had my own server. However I also recall wasting a looot of time configuring and maintaining that server. I'm willing to spend some to save time.
Can you share general numbers on this? I'm interested in which quotas you're spending money on the most.
