Oxygen generator or tank

Hello. Can anyone tell me if Oxireyes in Riberas is the best option for renting a portable oxygen tank or an oxygen generator? Or is there a better or less expensive option in Guadalajara?

Thanks in advance for any response.

Also check the medical supply place, near top of the hill in Ajijic, west of Colon on the lakeside of the Carretera.  Lydia, is the owner.....she has them.

Or, check Mercadolibre.com.mx and search for Concentrador de oxigenio
You can order whatever you need, sent directly to your home.
