If you're satisfied with an OEM ride, then Monroe QuickStruts are a cinch to install (assuming your hardware is not horribly corroded) and probably your cheapest option. While you're at it, put some SensaTrac shocks on the rear (although based on comments on the forum, the wagon's rear shocks are not as easy to replace as other Focii).
Also, the rear LCA cam bolt internally seizes on older Focii, resulting in a frozen toe setting and LCA's that only come off with a cutting tool. So, if you're being really proactive and plan to get an alignment anyway, then you might wanna think of some way of mitigating that corrosion.
