First, RevGKG - It's good to know there are other DTS people lurking on this board. I appreciated your comments, and heartily second them.
Wow. I go away for a week and come back to find this very interesting discussion. I am an almost-alum of DTS. I graduate this May with my ThM. And it only took me five years. Five great years that I in no way feel were wasted or that I could have been doing something "better" or more "productive" for God.
When I first came to DTS it was for a 2 year program. It soon became clear to me though, that God was requiring something different from me. So I changed to a ThM. After five years of "pricey" education I have absolutely no loans. I have paid all my bills on time. And I work a ministry job that is full time hours and only part time pay. If you are serious about DTS, you can get your degree without one single loan. It's truly amazing how God will provide for you. DTS is great about helping you with scholarships, and there are many other avenues to finance your education. But if you would rather not trust God to provide for the price - don't even think about going there.
There has been a lot of talk on this thread about the price and the number of hours. If you are going to decide on a seminary based on the price and hours then you should not go to DTS for a ThM. Go to another seminary where you can "do your time" for two years and get out and "get on with life." After all, heavens forbid that you actually have to change your plans to fit Gods. After all it's not like Jesus waited 30 years before He did what He came to do. (Please understand that my usage of sarcasm is not to offend but merely to get my point across)
As for the comment that was made about going somewhere else for a Masters and a Doctrate for the same time and money -- if your concern in being prepared for ministry is time and money don't go to DTS. And I would greatly caution you against going in the ministry at all. Anyone going into ministry should first be concerned about where God is leading them and once determining that they must have faith that God will provide for what He requires of them.
I love DTS, but I realize that it is not for everyone. There are others that God leads to a different seminary for an MDiv. If God leads you to do that - then go for it. But if God is leading you to DTS for a ThM then trust Him to provide. And your "extra" time spent getting the degree will not be wasted.
If you are seeking where to go to seminary because God has called you to go to seminary and you are trying to find out where He is sending you - consider DTS along with other seminaries.
