I needed some clubs for the little ones and found that the accu-length were getting good reviews and I like the idea that they are expandable for when the kids grow.

From most retailers they are 110-140 or so but on Amazon all but 1 size are less as outlined below.

FOUR!

Girls
AL500 - $42.18
AL1000 - $41.76

Boys

AL2000 - 57.79
AL3000 - 41.93

Thanks, OP!

My two boys have the 500 series, and the 2000 and 3000 will make a nice addition (4 sets for $200!!! - paid more for two 500 series!).

Too bad the 1000 series was $150 each. But these are great sets for those interested in learning golf. Not sure the 3000 series will work well with all the torque they should be able to generate at that age, but worse comes to worse, I'll think of it was getting two 2000 series at less than regular price with the 3000 series as free bonuses!

BTW: The way I see it...(looking at US 5%/95% growth charts) here are the possible Acculength series by age (depending on speed of height growth):
boys:
500 series: 2yo - 7yo
1000 series: 4yo - 11yo
2000 series: 6yo - 14yo
3000 - 8 - adult

girls:
500 series: 2yo - 7yo
1000 series: 4yo - 11yo
2000 series: 6yo - 16yo
3000 - 8 - adult

Deal is still alive for the 3000 series.

Something to consider:
These only come with maybe 1 set of 4 spacer inserts. (at least the 500 series I bought a year ago did). The 1000 series - 3000 series may not.

For 1000, 2000, and 3000 series, your child will need a total of 16 spacers = 5 years of use.
Year 1 = no spacer
Year 2 = 4 spacers (putter, 7-iron, PW, wood)
Year 3 = 4 spacers (putter, 7-iron, PW, wood)
Year 4 = 4 spacers (putter, 7-iron, PW, wood)
Year 5 = 4 spacers (putter, 7-iron, PW, wood)

Amazon has a set of 4 spacers for $9.95 (free shipping if your total = $25+)

golfsmith.com has them for $10. Every once in a while they'll have the F&F 10% off coupons -or- free shipping. I do not know if they can be combined, but golfsmith is a choice if you don't want to spend $25. I ordered 2 sets of spacers from them recently with free shipping...~$20.
