It's overpriced for what's in it. The 32mm, 17mm and 13mm plossl will be useful. The 8mm and 6mm will be so short on eye relief as to be nearly unusable. The Barlow is likely achromatic so will introduce chromatic abberation...not to mention it makes nearly redundant magnification on the usable eyepieces in the kit. It might move the exit pupil of the 8mm far enough out to make that more useable, but now your at 375x magnification which isn't usable on most nights or most objects. Color filters are neat for about 2 nights, then they'll wind up in a drawer never to see light again. The moon filter will be fine.
So the way I look at it is they want $175 on sale for 3 plossls, a moon filter and a shiny case. You could get essentially the same plossl kit and barlow from SVBony (it's all likely coming from the same factory anyway) for $75 and put them in a knockoff pelican case from Harbor Freight for $40 that's more rugged than the Celestron and still have $60 to spend.
If it were me I'd get a 32mm plossl and a set of "goldlines" (better eye relief and wider FOV) and put them in a knockoff case. You'll have spent about the same amount of money as the Celestron kit, but you'll have better EPs that won't need upgrading until you're ready to spend a decent bit more.
My two cents at least.
Clear skies!!
