Barlow + 15mm plossl may be be your best bet. An inexpensive but very useful addition. Word of warning with barlows: many 2x barlows end up giving 2.2-2.4x magnifications with some eyepieces, and it may well be that your 10mm barlows to become a 4-4.5mm, which would be really pushing the limits of seeing on many nights. A barlowed 15mm could be used more often in any case.
If you want a native short FL EP with generous eye relief, but don't want to pay vixen LV prices, the ED-2 from AOE for $79 might be a good option. Asimov himself gave the 9.5mm a good overall review (see iis reviews page). Care to comment, Asi?
