ionics glyder ?? this is ment to be a good pole, some nice video's on the website.
What size is it you wanting, if you can afford it id get the 25ft as youll reach all windows above cons and 3 town houses, I got 18ft and 25ft and find myself using the 25ft more often.
What makes the SLX worth waiting for?
If Alex has told you a definite date I'd wait. My 35ft SL-X is the only bit of kit I've spent a lot on and it has transformed my work.
