Hi Esseth,
I know I harp on about my dislike of barlows, however, I am nothing if adaptable. Here goes...
Here is an EP & barlow combo that will really put some punch into your scope, and give you the 'big eye lens' you are looking for:
GSO Superview 15mm & the GSO 3X barlow, and change left for $100 from Andrews.
I have this 15mm EP, & I love it. Very inexpensive & it works so, so well. Its eye relief is good too, though might be a little tricky with glasses, but not squashed up to it. I work this EP in combination with its bigger brother, the Superview 30mm, a 2" EP. Both have brilliant 68degrees field of view. If your focuser takes 2" EPs, I highly recommend this EP too for your dob. They perform exceedingly well for their price.
The high power EP I use is a Meade Series 5000 Plossl 5.5mm, which does have a relatively small eye lens, but not as small as the standard Plossls. Much, much easier EP to use than my Vixen LV5mm, & half the price. The Vixen has a large eye lens,but no eye relief in comparison, & a much more restircted field of view, 40deg's compared to 60. makes for much easier use at high power with a dob. Bintel has this diminuative EP at $129.
Just my current experience with my EP collection. All these perform well in all my scope, except only my big dob has a 2" focuser. I don't need much else right now. Hope it helps.
