John, I read Phils original post as indicating he wanted to buy one eyepiece AND a barlow.

Geoff,
I just re read Phils original post and your correct, he did plan on buying the GS 1.25" barlow and the 15mm Superview, apologies.
Phil,
I don't recommend you buy the 1.25" GS barlow, I have used it several times in a variety of scopes and with a number of eyepieces and can only rate it fair. You have a good scope in the LX90 so don't downgrade the scope by using cheap accessories with it. Its a bit like buying a Mercedes and then putting recaps on it when its 1st set of tires wear out, false economy. If you want to get a barlow the minimum I would consider is the Orion Shorty Plus which costs about $130.
Your best option IMO is to go and buy the 18mm and the 9mm UO HD orthos. This will cost you about $240, but the image quality is superb, albeit with a slightly narrow FOV. Sharpness, contrast and light transmission of these eyepieces is as good as any premium eyepiece and they deliver perfect star images across the entire field of view in scopes slower than F5 or so.
