Can anyone explain the RockShox range to me?

[NWMark]

Keeping an eye out for a replacement set of rockshox for my bike and im confused.

I take it the range goes something like Dart < Tora < Recon < Reba (where does boxxer fit into this)

But its all the additional bits.

Solo Air
Dual Air (more air than solo?)
U-Turn
Coil (a spring i presume)
SL
SID

and then theres the numbers, 302, 426, 351 etc etc

Anyone shed any light on this please?

what does the number 335 refer to, ive seen some with numbers and some without, very confusing.

Cheers
