Merida Juliet 500 W vs Merida Matts Lite XT-Edition

[Matshi]

I'm a lady rider looking to upgrade from my 26" Raleigh Nomad to something better as I ride a lot more now.

 

I've seen a new 2014 Merida Juliet 500W, and a second hand 2013 Merida Matts Lite XT-edition both within my budget.

 

I'm looking to spend max R13K on a hardtail, 26er or 650B.

I'm only 154cm so would like something relatively light and compact (15" frame).

I do a lot of single track riding.

 

Any advice on whether I should go new or secondhand, and if there are other models I should consider would be appreciated.
