May I suggest a Tele Vue 8mm Plossl. It is a very high quality eyepiece and will give nice bright views of planets at 150x in your telescope. Current price is $115.00 at BINTEL. This will be a far superior eyepiece than your 10mm Skywatcher.

I also recommend a 32mm Plossl at some stage for low power use and once again Tele Vue make a very fine eyepiece in this size.

How much money do you want to spend in the long term? You could get a Tele Vue 2x Barlow and a 15mm and 11mm Tele Vue Plossl in lieu of the 8mm Plossl but this is a lot more expense but could be a long term solution. To start with I would first buy the 15mm. It will give you some amazing images of star clusters and nebulae. If your interest is planets, go the 8mm and even with a 2x Barlow later you will be able to achieve 300x magnification althought there are not many nights when this power is useful, but when the air is steady, 300x is spectacular on planets.

The only reason I mention Tele Vue is that you mentioned quality and I can think of no better product and their Plossl range is priced very favourably.

Just to clarify:

If you only want to spend around $100 and buy just one item and nothing else for a while, get the Tele Vue 8mm Plossl. You will not be disappointed.

You can later add other Plossls and Barlows if you want.

If you want to spend more now then the 15mm and 11mm plus 2x Barlow would give you 5.5mm, 7.5mm, 11mm & 15mm which is more than enough for high power viewing.

Note you could also get the Tele Vue 15mm and 2x and 3x Barlows giving you 5mm, 7.5mm, 15mm.

There are many options and of course it can get expensive but purchases can be spread over time and the eyepieces can be used on any telescope.

Note Tele Vue do not make a Plossl under 8mm so if you want a 6mm then either an 11mm with 2x Barlow or 20mm with 3x Barlow will be close and both these options will provide for a more comfortable view due to better eye relief.

If I were you I would buy the 8mm now and see what a difference in image quality you get over the SW 10mm. It will be noticeable.
