@FlyingMac: may we extend that to "go for something Rotax-powered, at least for your basic trainer"
@Parson: a good remark, but a club needs to make sure to invest for the best interest of its members. That means low hourly rates which in turn means flying a lot of hours. It will depend on membership if aerobatic or taildragger planes will draw enough interest. In my observation (on the other side of the small pond) clubs only have such an exotism when they have at least five more conventional planes - microlights included.
