second scope - which one? Orion ShortTube 4.5 EQ or SkyQuest XT 4.5

Hello all,

My first scope was a Meade Polaris 114EQ-D purchased at Service
Merchandise a few years back. I want to know purchase a second scope
and even though I would really like to get a 6" Dob, the finances only
allow for the $199 models.
The choices are the Orion ShortTube 4.5 EQ or the Orion SkyQuest XT
4.5. WHich is the better one of these two choices? I like the EZ
Finder scope on the Shorttube but I know that is not a clear reason to
choose one or the other. Does anyone have experience with either of
these models or another brand that would be better to replace my
Meade.

The Meade Polaris gave me great views as a begineer and still are
impressive. If I get either one of these scope, will I have the same
scope that I have now (upgraded the eyepieces to Orion Explorer II's)
or will either one of these blow me away compared to the Meade
Polaris?

I'm just afraid of getting a different version of the same scope and I
know that the 6" dob would be a better scope than these, but yet
again, need to stay at $199.

Any recommendations or comments on these would be appreciated.
Again, any other company scopes that are better than what I have now
for the same price ($199) would be helpful.

Thanks,
Jim Fedina
