After doing a little searching on the Web, I found a tennis warehouse forum upon which a poster helpfully listed the following pro shops in Baires. We're going to go by one today with the girls, will report back.
(Hey, if I play this right, I could post and provide all of the answers in my own thread. Maybe it's a way to build up my posts so I'm not a "Newcomer" anymore!)
If you are searching for good prices.. don't buy in BA..
Pro shops.. you'd better check the address in the internet
Hector tenis- nice selection of racquets, prices ok (for BA), reasonable good knowledge of equipment, nice selection of used ones, no credit cards.- located in Av. Congreso & Ciudad de la Paz - Belgrano.
Halcry tennis - popular, babs distribuitor, very expensive, credit cards. Lavalle y Florida - Downtown also in Av del Libertador & Sucre - Belgrano.
Raqueton - nice selection of racquets, demoes, prices ok (for BA), no credit cards. Av. del Libertador & Sucre - Belgrano

hey, there are a surprising number of tennis stores here, and though I don't know much about how good the prices are, there is a pretty nice one on the corner of Marcelo T. de Alvear and San Martin, a block away from Plaza San Martin in the Microcentro/Retiro area. let me know if you need any more help finding things,
