Next accessory?

I have earned 150 $ by working a little after school and would like to spend the money on new equipment for my 10” reflector. I have the following ideas:

1. A 9x50 finderscope (I currently have a 6x30)

2. A 2” focuser (I currently have a 31.7 mm)

3. A 30 mm Ultima eyepiece

4. Motor drives

If anyone else has another suggestion please let me hear it. I have a limiting magnitude of around 5.0 where I live. I don’t do astrophotography. Are there any problems associated with upgrading from 1.4” to 2” focuser? I already have a 25 mm eyepiece (48x vs. the 30 mm’s 40x) but the apparent FOV of the 25 mm is only 40 degrees which gives me a 25’ bigger field diameter in the 30 mm. Is that worth it (I don’t think my 25 mm would get much use afterwards with only 8x magnification difference). My 25 mm is brighter in some places of the field than in others. Is that because I have reached the lower magnification limit of my telescope? Based on this information what would you recommend me to buy?
Any help will be appreciated.
Thanks

A two inch focuser is a nice thing but decent 2 inch eyepieces are expensive so at this time you would probably not be able to afford both.

A decent 32 mm eyepiece would probably be a nice addition, the Ultima is a good one but I think the standard 32 Plossls would probably be nice too.

Drives, or at least one drive would be nice, if you have an EQ mount. Might be able to buy the drives and a decent 32mm plossl.

The finder would be nice too....

Nicholas,
You didn't mention where you're observing from.
I know that when I went from a 6x30 to a 9x50 finder in my light polluted Manhattan, it was SUCH an improvement!
I think a 9x50, the 30 Ultima.......maybe a Rigel Quickfinder (smaller footprint, less weight, less balance problem)
Sounds good to me,
-Curtis
